Over the past decade, Oslo has turned ambitious climate goals into concrete results – from zero-emission construction sites and green transport to climate-smart urban planning.

As the IPCC leadership and authors gather in Oslo to advance the Special Report on Climate Change and Cities, Governing Mayor Eirik Lae Solberg invites key partners from business, academia, government, and international networks to Oslo City Hall.

Join us at Oslo City Hall on January 12th, 2026, for an afternoon filled with inspiring talks, examples from Oslo’s green industries, and discussions on what’s next: how city-level action connects to national and global climate goals.

The day concludes with a reception for IPCC authors and event participants in the City Hall, co-organized with the Norwegian Environment Agency and the IPCC.

This event is by invitation only.
